Why should I update my BIOS? Or why I shouldn't?

It is normal for users to keep their computer system updated. It isn't even just normal, it is also required. Updating is basically done for security reasons. The updating requirement includes many of your computer system's software or programs including the antivirus software and even your Operating System like Windows itself. In most cases, they probably update automatically by default or you need to update them manually with a few mouse clicks.
